Answer:
20 units
Step-by-step explanation:
As you know that the quadrilateral is a square, you’ll just have to find the length of one side and multiply it by four. We can count and see that one side is 5 units.
5 * 4 = 20 units
You can also add the length of each of the four sides.
5 + 5 + 5 + 5 = 20
